After creating an assessment, when you go to its settings page, there is a link to “expand all” settings, that becomes a “collapse all” link after pressed. The expand all link will open each settings dropdown in the menu, but does not move the corresponding arrows in the correct direction, and the same goes for collapse. Expand all should make all headers “active” and collapse should remove “active” highlighting from each header.
